Functional Descripti on

These devices are 16-bit, D-type latches, designed for use in

bus applications requiring high speed and low power. They can

eithe r be used as two independe nt 8-bi t lat ches, or as a si ngle

16-bit latch by connecting the Output Enable (OE ) and Latch

(LE) inputs. The outputs are 24-mA balanced output drivers

with current limiting resistors to reduce the need for external

terminating resistors and provide for minimal undershoot and

reduced g round bounce. Flow-throug h pino ut and small shrink

packaging aid in simplifying board layout.

The CY74FCT163H373 and CY74FCT163LDH373 have “bus

hold” on the data inputs, which retain the input’s last state

whenever the source driving the input goes to high impedance.

This eliminates the need for pullup/down resistors and pre-

vents float ing inputs .

The CY74FCT163373 and the CY74FCT163LD373 are

designed with inputs and outputs capable of being driven by

5.0 V buses, allowing them to be used in mixed voltage

systems as translators. The outputs are also designed with a

power off disable feature enabling them to be used in

appli cations requiring live insertion.

Lite Drive is a tradem ark of Cypress Semiconductor Corporation.

Note:

1. On the CY74FCT163H373 & CY74FCT163LDH373 these pins have “bus hold.

2. H = HIGH Voltage Level. L = LOW Voltage Level. X = Don’t Care. Z = High Impedance. Q0=Previous state of flip-flop.

3. Operation beyond the limits set forth may impair the useful life of the device. Unless otherwise noted, these limits are over the operating free-air temperature

range.

4. With the exception of inputs with bus hold, unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground.

5. Typical values are at VCC=3.3V, TA = +25°C ambient.

6. This parameter is guaranteed but not tested.

7. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample

and hold techniques are preferabl e in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of

a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter

tests, IOS tests should be performed last.

8. Per TTL driven input; all other inputs at VCC or GND.
